xci: osa: Add initial dynamic inventory from PDF/IDF files

The PDF and IDF files contain all the information we need for the
virtual XCI deployment, so we can use it to create a dynamic inventory
and get rid of all the static ones which could easily get outdated
as PDF and IDF files evolve over time.

This inital version of the dynamic inventory contains a lot of
unnecessary generated information but we do that in order to ease
the migration from static files to the dynamic inventory. The dynamic
inventory will be improved in the future as we consume more and more
information from the PDF and IDF files.
